MOWlNG-NIACHINE.

SPECIFICATION forming part of Letters Patent No. 789,308, dated May 9, 1905.

Application filed March 8, 1904. $e1'ia1No. 197,127.

To all whom it may concern:

Be it known that I, Gnonen WILSON, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Mowing-Machines, of which the following is a specification. 1

The object of this invention is to construct a mowing-machine in which the clutch mechanism employed to form a connection between the axle and gearing is operated by the movement of the hand-lever used to raise and lower the cutting apparatus.

In the accompanying drawings, Figure 1 is a perspective View of the mowing-machine in which the cutting apparatus is raised. Fig. 2 is a similar View in Which the cutting apparatus is lowered into working position. Fig. 3 is a top view of the clutch mechanism. Fig. 4 is a perspective view of the mowing-machine as seen from the cutting apparatus side- Fig. 5 is a vertical section through the clutch mechanism.

The main frame of the machine is the same as found in general use, comprising the bed 1 and tongue 2. To the bed is pivotally connected the coupling-bar 3, having the yoke A connected to its outer end. The shoe 5 has a pivotal connection with the yoke. A pushbar 6 has a pivotal connection with the bed of the machine, also with the yoke.

A bell-crank lever 7 has a pivotal connection with the bed of the machine. A link 8 forms a connection between the yoke 4. and one arm of the bell-crank lever.

From the bed of the machine extends a quadrant 9, having a notch 10 in its forward portion. To the center of the quadrant is pivoted a hand-lever 11, provided with the usual dog and thumb-lever.

A stud 12 extends from the hand-lever and upon which is pivoted a segment 13, having a projection 14 at one end and a projection 15 at its other end and moving in contact with the hand-lever and guided in connection therewith by the lip 16, extending from the handlever over the segment. A flat spring 17 is supported by the stud 12 and its free end rests against the segment, thereby holding the segment against the hand-lever.

A rod 18 has one end connected to the segment and its other end connected to the bellcrank lever 7.

A foot-rest 19 has a connection with the segment l3 and extends rearward therefrom.

A bell-crank lever has a pivotal connection with the bed of the machine, an arm 20 of which has a horizontal opening through which a rod 21 passes, supporting a pin in one end. A coiled spring 22 surrounds the rod 21 and is located between the arm 20 of the bellcrank lever and the pin in the end of the rod. The other end of the rod 21 has a pivotal connection with the hand -lever 11 by surrounding the stud 23, extending from the handlever.

Upon the axle 2 1 is loosely mounted a gearwheel 25, which has the usual gear connection with the crank-head and drives the knife. One face of this gear-wheel is provided with serrations 26, forming one-half of a clutch mechanism.

A sleeve 27 has a feather and slidable connection with the axle, and one end is provided with teeth 28, adapted to engage the serrations 26 of the toothed wheel 25. The sleeve is provided with an annular groove 29, within which is located a fork 30, having its shank portion guided in a way 31, formed in the bed of the machine. From the end of the shank portion extends an eye 82, passing through an opening in the way 31. A rod 33 has one end connected to the eye 32 and its other end to the arm 34 of the bell-crank lever.

A spring 35 serves to hold themovable section 27 of the clutch mechanism in engagement with the toothed wheel 25.

I/Vhen the hand-lever is in its upright position, the cutting apparatus will be lowered into working position and the slidable portion of the clutch will be in engagement with the toothed wheel 25, thereby connecting the axle with the knife, and the hand-lever willbe locked in engagement with the quadrant 9.

The cutting apparatus can be raised by means of the hand-lever 11 and held in its elevated position by the dog of the hand-lever resting in contact with the rear face of the quadrant.

When the cutting apparatus is raised by the hand-lever, the movement of the hand-lever rearward will draw on the rod 21 and through the spring 22 will move the bellcrank lever and disengage the movable section of the clutch from the toothed wheel 25, thereby breaking the connection between the axle and knife, and upon moving the handlever forward the movable section of the clutch will be allowed to enter into engagement with the toothed wheel 25.

As the hand-lever has no direct connection with the cuttingapparatus, the projection 16, extending therefrom, must engage the projection 15, extending from the segment 13, thereby forming its connection with the cutting apparatus.

l/Vhen the hand-lever is in its forward locked position, the cutting apparatus can be raised and lowered by means of the foot of the attendant pressing down on the extension 19, which will rock the segment independent of the hand-lever and independent of the clutch mechanism.

To the bed of the machine is pivoted a lever 36 and having a position with relationhto the eye 32 of the slidable section of the clutch mechanism that it will engage the eye and disengage the section 28 from the toothed wheel 25. This lever is employed when the machine is in the field and without raising the cutting apparatus the clutch connections can be broken.

I claim as my invention In a mowing-machine, the combination of a hand-lever, gearing for driving the knife, a clutch-toothed section having a connection with the gearing, asliding clutch-toothed section, a pivoted bell-crank, a connection between the sliding clutch-section and one arm of the bell-crank, a rod connected to the handlever and passing through the other arm of the bell-crank, and a spring surrounding the rod one end resting against the arm of the bellcrank through which the rod passes.
